The electric current, in turn, creates its own magnetic field—one that ... which increases the field still further. This self-sustaining loop is known as the geomagnetic dynamo.

Scientists create magnetic device to capture electricity from Earth’s rotational dynamicsA wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...
DC SQUID: A DC SQUID consists of two Josephson junctions connected in parallel in a superconducting loop. When an external magnetic field is applied, it induces a current in the loop, which is ...
No matter how its done, with whatever level of fakery, magnetic levitation just ... with some control electronics to adjust the field strength and close the loop. But, there may be another way ...
When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...
SOME preliminary results have been obtained from an investigation being undertaken at College, Alaska, concerning the correspondence of the Earth's magnetic field micropulsations 1 with pulsating ...
